The soap molecules then gather up into droplets in which all the "water-loving" ends face outward.
The physics of a spray dryer are like that of a diesel engine's fuel injector in that it atomizes liquid (insulin or gasoline) into droplets.
Although electrospun bovine serum albumin does not actually break up into droplets, the resulting threads have been so short and irregular as to be useless.
Such particles act as nuclei for the condensation of water vapour into the droplets of which clouds are composed.
My smoky breath turns to liquid as it hits the window and, if I rub the mist into heavy droplets, I can make it trickle down the glass.
What is becoming clearer with time is that the chemical dispersants typically used in clean-up efforts to break masses of oil up into small droplets does more harm than good.
BBC: Deepwater Horizon: Gulf of Mexico 'deep-cleaned' itself
This vapour condenses into a trail of droplets as a charged particle zooms through it.
When these charged droplets come into contact with the surface of the print they collect any substances deposited on it, creating a thin liquid film.
Using a particle accelerator, he demonstrated that cosmic rays colliding with molecules in the atmosphere can, in fact, cause gaseous water vapor to condense into cloud-forming droplets.
Snyder, who spent four years on turbine engines at a Cat subsidiary, ran dozens of two- and three-week-long simulations on a minisupercomputer, crunching 10 million equations each time, to design a new nozzle that would turn insulin into the right-size droplets.
Such clouds would persist for an unusually long time because small water droplets are less likely than big ones to turn into rain.
It consists of condensed water droplets and is associated with a column of air that rotates as it is drawn into the cloud.
Twenty million metric tons of sulfur dioxide mixed with droplets of water, creating a kind of gaseous mirror, which reflected solar rays back into the sky.
